如何组合这两个 MS Access 查询？

Question

SELECT 
    USERINFO.Name, USERINFO.SSN, USERINFO.Badgenumber, 
    FORMAT(CHECKINOUT.CHECKTIME,"yyyy") AS [YEAR], 
    FORMAT(CHECKINOUT.CHECKTIME,"mmmm") AS [MONTH], 
    FORMAT(CHECKINOUT.CHECKTIME,"dd") AS DAYS, 
    FORMAT((Min(CHECKINOUT.CHECKTIME)),"hh:mm am/pm") AS TIMEIN, 
    FORMAT(CHECKINOUT.CHECKTIME,"AMPM") AS [AM/PM], CHECKINOUT.CHECKTYPE
FROM 
    CHECKINOUT 
INNER JOIN 
    USERINFO ON CHECKINOUT.USERID = USERINFO.USERID
WHERE 
    (CHECKINOUT.CHECKTIME >= DATEVALUE(PERIOD_START) AND
     CHECKINOUT.CHECKTIME < DATEADD("d", 1, PERIOD_END) AND
    USERINFO.Name = Insert_Name) AND 
    CHECKINOUT.CHECKTYPE = "I"
GROUP BY 
    CHECKINOUT.USERID, USERINFO.Name, USERINFO.SSN, 
    DateValue(CHECKINOUT.CHECKTIME), FORMAT(CHECKINOUT.CHECKTIME,"AMPM"), 
    USERINFO.Badgenumber, FORMAT(CHECKINOUT.CHECKTIME,"mmmm"), 
    FORMAT(CHECKINOUT.CHECKTIME,"yyyy"), FORMAT(CHECKINOUT.CHECKTIME,"dd"), 
    CHECKINOUT.CHECKTYPE
HAVING 
    (((USERINFO.Badgenumber) < "8000"))
ORDER BY 
    USERINFO.Name, Min(CHECKINOUT.CHECKTIME);

此查询的时间是

SELECT 
    USERINFO.Name, USERINFO.SSN, USERINFO.Badgenumber, 
    FORMAT(CHECKINOUT.CHECKTIME,"yyyy") AS [YEAR], 
    FORMAT(CHECKINOUT.CHECKTIME,"mmmm") AS [MONTH], 
    FORMAT(CHECKINOUT.CHECKTIME,"dd") AS DAYS, 
    FORMAT((Max(CHECKINOUT.CHECKTIME)),"hh:mm am/pm") AS TIMEOUT, 
    FORMAT(CHECKINOUT.CHECKTIME,"AMPM") AS [AM/PM], 
    CHECKINOUT.CHECKTYPE
FROM
    CHECKINOUT 
INNER JOIN 
    USERINFO ON CHECKINOUT.USERID = USERINFO.USERID
WHERE 
    (CHECKINOUT.CHECKTIME >= DATEVALUE(PERIOD_START) AND
     CHECKINOUT.CHECKTIME < DATEADD("d", 1, PERIOD_END) AND
    USERINFO.Name = Insert_Name) AND
    CHECKINOUT.CHECKTYPE = "O"
GROUP BY 
    CHECKINOUT.USERID, USERINFO.Name, USERINFO.SSN, 
    DateValue(CHECKINOUT.CHECKTIME), FORMAT(CHECKINOUT.CHECKTIME,"AMPM"), 
    USERINFO.Badgenumber, FORMAT(CHECKINOUT.CHECKTIME,"mmmm"), 
    FORMAT(CHECKINOUT.CHECKTIME,"yyyy"), FORMAT(CHECKINOUT.CHECKTIME,"dd"), 
    CHECKINOUT.CHECKTYPE
HAVING 
    (((USERINFO.Badgenumber) < "8000"))
ORDER BY 
    USERINFO.Name, Min(CHECKINOUT.CHECKTIME);

此查询超时，

如何将这 2 个查询组合在一起？

Answer 1

除了各自的 WHERE 子句中的单个条件外，这些查询看起来是相同的。第一个查询是这样的：

CHECKINOUT.CHECKTYPE = "I"

而第二个有这个

CHECKINOUT.CHECKTYPE = "O"

我觉得你可以把这两个条件结合起来，如下：

WHERE ... AND CHECKINOUT.CHECKTYPE IN ("I", "O")

完整查询：

SELECT USERINFO.Name,
       USERINFO.SSN,
       USERINFO.Badgenumber,
       FORMAT(CHECKINOUT.CHECKTIME,"yyyy") AS [YEAR],
       FORMAT(CHECKINOUT.CHECKTIME,"mmmm") AS [MONTH],
       FORMAT(CHECKINOUT.CHECKTIME,"dd") AS DAYS,
       FORMAT((MIN(CHECKINOUT.CHECKTIME)), "hh:mm am/pm") AS TIMEIN,
       FORMAT(CHECKINOUT.CHECKTIME,"AMPM") AS [AM/PM],
       CHECKINOUT.CHECKTYPE
FROM CHECKINOUT
INNER JOIN USERINFO
    ON CHECKINOUT.USERID = USERINFO.USERID
WHERE CHECKINOUT.CHECKTIME >= DATEVALUE(PERIOD_START) AND
      CHECKINOUT.CHECKTIME < DATEADD("d", 1, PERIOD_END) AND
      USERINFO.Name = Insert_Name AND
      CHECKINOUT.CHECKTYPE IN ("I", "O")     -- here is the change
GROUP BY CHECKINOUT.USERID,
         USERINFO.Name,
         USERINFO.SSN,
         DateValue(CHECKINOUT.CHECKTIME),
         FORMAT(CHECKINOUT.CHECKTIME,"AMPM"),
         USERINFO.Badgenumber,
         FORMAT(CHECKINOUT.CHECKTIME,"mmmm"),
         FORMAT(CHECKINOUT.CHECKTIME,"yyyy"),
         FORMAT(CHECKINOUT.CHECKTIME,"dd"),
         CHECKINOUT.CHECKTYPE
HAVING USERINFO.Badgenumber < "8000"
ORDER BY USERINFO.Name,
         MIN(CHECKINOUT.CHECKTIME);

出于参考目的，如果两个查询的逻辑差异很大，但是两个查询在 SELECT 子句中具有相同的结构，我们可以对两个查询执行 UNION。
